CHARLES F. PEASE, OF CHICAGO, ILLINOIS., ASSIGNOR OF ONE-HALF TO WILLIAMS, BROWN & ISARLE, OF PHILADELPHIA, PENNSYLVANIA, A FIRM;

:BLUE-PRINT WASI-IIN G AND DRYING MACHINE.

To all whom 'it may concern:

Be it known-that I, CHARLES FsPEAsE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinols, have invented certain new and useful Improvements in Blue-Print Washing and Drying Machines, of which the following isa specification.

My invention relates to blue print washing and drying machines andis particularly adapted for use in connection with what is known as a continuous printing machine, a1- though the use of the latter is not essential.

The objects of my invention'are to provide a simple and reliably constructed machine of the yclass above mentioned, wherein not only the process of washing and drying blue prints may be effectively accomplished, but wherein the blueprint is subjected to a bath in a solution of potash, or other blue print intensifying solution to so construct my improved a paratus as to insure the positive ceding of the blue print paper through the various baths and drying chambers at a uniform speed; to rovide improved means for rapidly and uniiorinly drymg printed paper and to roduce other improvements, the details OP construction and arrangement of lparts of which will be more fully pointed out ereinafter. These objects I attain in the manner illustrated in the accompanying drawing in which,

Figure 1 is a plan view of my improved ap' paratus showing a strip of blue print paper 1n position for passing therethrough, and Fig. 2 is a longitudinal section on line 2 2 of Fig. 1.

imilar numerals refer to similar parts throughout the several views.

In carrying out my invention I employ a suitable upright frame work comprising vertical standards 1, upper longitudinal side frame pieces 2 and transverse frame pieces 3. Mounted on opposite sides of the forward and rear ends of the frame thus constructed, are upwardly projecting bearing brackets 4 and 5, each of the latter having formed in its upper portion a downwardlyextending bearing recess 6 which is enlarged in its upper ortions on one side to form a shoulder 6a. etween the lower portions of the opposing brackets 4 are journaled the shaft or spindle ends 7% of a transverse roller 7, while a similar roller 8 is likewise journaled between the Specification of Letters Patent.

Application filed December 5, 1906. Serial N o. 346,479.

Patented June 23, 1908.

en of the shaft 7 a is mounted a power or belt wheel 12 which is adapted to carry an operatin belt, such as is indicated at 12a. This sha t or spindle 7a also carries a s rocket wheel 13, while the corresponding en s of the roller spindles 9el and 10a carry similar sprocket wheels 14 and 15. A fourth and corresponding sprocket wheel 16 is carried on one end of the spindle 8 of the roller and these sprocket wheels 13, 14, 15 and 16 are connected lby an endless sprocket or driving chain 17. l Loosely mounted in the recess 6 of the brackets 4 are the ends of a transverse shaft 18 whichcarries. thereon at desirable intervals feeding disks 19, the latter normally bearing upon the periphery of the roller 7. A wringing or drying 'roller 20,

l preferably formed of soft rubber, has its end spindles within the recesses 6 of the brackets 5, said roller 20 normally contacting with the roller 8. It will be observed that the chain belt 17, in its central portion passes over an idle sprocket wheel 21, which is rotatably mounted on the outside of one of the frame pieces 2.

22, 23 and 24 represent, respectlvely, tanks or reservoirs which are suitably supported from the frame ieces 2 and which, as shown, are A res ective y arranged beneath the spaces whic exist between the rollers 7 and 9,"9 and 10 and 10 and 8. y

Adjacent to, and on the outside of'the roller 8 is a drying case 25 and rotatably mounted in this casing is a air of cylinders 26 and 27. One end of eac lof these cylinders is provided with a hollow bearing proection or trunnion 28 and through these hol'- low bearings extend gas )ipes 29 and 30, the latter leading through the ends of said cylinders and terminating at points near the opposite ends thereof. 'lhe pipes 29 and 30 are provided with suitable burner projections 31 and the outer ends of said pipes are connected with a gas supply pipe 32.V '[he operation of lighting the gas burners 31 may be i while the intermediate tank 23 is provided accomplished by the insertion of a lighted taper through o enings 25a and 26a formed respectively in t ie casing or housing 25 and the adjoining ends of the cylinders. The bearing end shafts or spindles 26b and 27 b of the cylinders 26 and 27 carry sprocket wheels 33. Opposite the rollers 2O and 8 the casing 25 is formed in its upper portion with a transverse opening 34 and a similar, although larger opening 35, is formed in the opposite `end of said casing in the lower portion thereof.

36 and 37 represent contacting rollers, which are journaled on the outside of the opening 25, the lower roller 36 having its bearing shaft or end spindle rotatably mounted in upright brackets 38 which correspond in constructionl withvthe brackets 4 and 5, thesaid brackets 38 being rovided in their upper portions with vertica recesses 39 having off-sets 40. TheA upper roll 37 has its bearing spindles bearing loosely in said bracket recesses 39.

4l represents an endless sprocket chain which passes over a small sprocket wheel 42, which 1s carried on the roller spindle 8, outside o'f the sprocket wheel 16. The chain 41 runs, as indicated more clearly in dotted lines in Fig. 2 of the drawing', from the upper side of the sprocket wheel 42 outward about the outer sprocket wheel 33, thence up and over the inner sprocket wheel 33, thence outward over a small s )rocket wheel 43 on the end of the bearing s aft 36a of the roller 36, from which said chain leads inward and u ward to the sprocket wheel 42, referab y assing over an idle sprocket whee indicated 1n dotted lines at 44 in Fig. 2.

45 represents a water supply pipe which is arranged adjacent to the frame 1-2-3 and which has arms 45a and 45b leading transversely across said frame above the latter and on the inner sides of and adjacent to the rolls 9 andS, said pipe arms being suitably erforated and the perforations thereof being inclined forward and downward.

Irl-utilizing my invention the tanks 22 and 24 are filled or partially filled with water with a desirable quantity of blue print intensifying solution.

In operation the blue printed paper strip, which in the drawing is indicated at 46 passes from the printer, or other suitable source of supply, over the roll 7 thence downward into the lower portion of the tank 22, thence upward over' the roller 9 from which said paper strip passes downward into the tank 23, u ward over the roller 10, downwar`d into t e tank 24, upward between the rollers- 8 and 20, thence forward through the opening 34 of the casing 25, about the heating cyl. inders 27 and 26 and out between the delivery rolls 36 and 37. In order to" insure the paper strip being held taut within the tanks,

suitable cylindrical bodiesor rolls, such as are indicated at 47 are-caused tobe su ported by the paper strip in each of the tanks 22, 23 and 24. In the passing of the blue print through the tank 22, the print is subjected to the washing action of the water contained in said tank, but to insure the thorough washing of the printI have provided the water pipe arm 45a', the Water sprays from which are thrown directly against the face of the blue print before it passes about the roller 9 and enters the tank 23. Having been subjected to the intensi ing action of the solution of the tank 23, t e paper strip after passing over the roll 10 is subjected to the washing action of the water contained in the tank 24 which is followed by the final washing action of the water spray from the pipe 45". The gas burners 31 having been previously ignited, it is obvious that not only will the atmosphere contained in the casing 25 become heated, but that the heat imparted to the cylinders 26 and 27 will have the effect of thoroughly drying the blue print aper before the latter is delivered between the" rolls 36 andy 37.

In the operation which I have described, it will be understoodthat the various paper carrying rolls have motion imparted thereto through the medium of the power wheel 12 and the various sprocket wheels and chains heretofore described. It will also be understood that in the passage of the wet blue rint paper over the various rolls, the surace of said rolls Awill become sufficiently moistened to adhere thereto, during its passage over the rolls, thus preventing an tendency of the paper to slip over the ro ls and at the Sametime insuring a uniform speed of the paper over the rolls.

From the construction and operation described, it will be readily understood that my improved apparatus is simple in construction an that the same can be readil operated by persons unskilled in the art of lue printing.

Having fully described my invention I claim:

In a blue print finishing machine, a series of liquid containing tanks, means for feeding a prlnted strip therethrough, brackets arran ed at the sides and adjacent each end of sai series, fixed rollers having their shafts or trunnions journaled vbetween said brackets at each end of said series, each of said brackets having an approximately vertical recess therein and being provided with a shoulder adjacent the up er end of said recess, said recesses and saldp shoulders being adapted to support'rollers therein superposed upon said fixed rollers, a removable shaft having a plurality of transversely disposed disks mounted thereon journaled within said recesses, a pair of said brackets at one end of said series, and
